Abstract:
BACKGROUND: Oligodendrocyte precursor cell transplantation is one of the keys to the treatment of white matter damage in premature infants. At present, there is a lack of research on the comparison of oligodendrocyte precursor cells induced by neural stem cells derived from human fetal brain cultured in vitro in different vessels worldwide. OBJECTIVE: To observe the morphology of human oligodendrocyte progenitor cells and pre-oligodendrocytes in different cell culture vessels (6-well plates, 24-well plates and T25 flasks). METHODS: The 6-well plates, 24-well plates and T25 flasks were used as culture vessels to culture human oligodendrocyte progenitor cells and pre-oligodendrocytes. The characteristics of human oligodendrocyte progenitor cells were identified by immunofluorescence staining and flow cytometry. The morphology of cells was observed by an ordinary light microscope. Cell counts were performed according to cell morphology and statistical analysis was performed. RESULTS AND CONCLUSION: (1) The oligodendrocyte progenitor cell body was round and the bipolar protrusions were bead-like; the pre-oligodendrocyte protrusions were more than two poles, and did not bifurcate. (2) The ratios of oligodendrocyte progenitor cell morphology in the oligodontia lines were significantly higher in the 6-well plates than those in the 24-well plates and T25 flasks (P < 0.05), followed by T25 flasks and 24-well plates. Morphological ratios of pre-oligodendrocytes were significantly higher in the 24-well plates compared to the 6-well plates and T25 flasks (P < 0.01), followed by T25 flasks and 6-well plates. (3) The cells cultured in the 6-well plate had fewer dregs, and the morphology, vigor and growth were better than those of the other culture vessels. (4) According to morphological view, 6-well plates are more suitable for oligodendrocyte progenitor cell growth, and 24-well plates are more suitable for pre-oligodendrocytes growth.
